COMB ATTACHMENT FOR ELECTRIC SHEARS Filed Jun 12. 1969 2 Sheets-Sheet Immwm U V O mm 2 United States Patent Office 3,581,396 Patented June 1,1971 US. Cl. 30-201 6 Claims ABSTRACT OF THE DISCLOSURE A double combattachment for double action electric hair shears in which the cuttingaction is longitudinal rather than transverse.

The invention relates generally to instruments for cutting hair and moreparticularly to double edged combs for use with electric shears.

It is old in the art to provide snap-on single combs for use on hairclippers to mechanically establish the length to which the edge of thehair will be clipped.

Double acting electric shears have just been introduced for cutting hairbeyond the edge or fringes on which clippers are used. Usually hair iscut an estimated length by hand shears as it is combed out with a handcomb.

It is an object of the invention to provide means for mechanicallyestablishing the length hair is to be cut rather than by estimation.

Another object of the invention is to provide a double comb forattachment on electric shears for combing the hair out in oppositedirections for simultaneous cutting by the double action electricshears.

Another object of the invention is to provide positive snap-on catchesfor rigidly attaching a double comb to an electric shear.

Other object sand a clearer understanding of the invention may be had byreferring to the following description and claims, and the drawings inwhich:

FIG. 1 is a plan view of the invention operatively attached to electricshears,

, FIG. 2 is an enlarged isometric view exploded to show the variousparts of the invention and their relative positions,

FIG. 3 is a perspective view from the bottom of a latching device,

FIG. 4 is an under view of the preferred embodiment of the invention,

FIGS. 5, 6 and 7 are end views of the preferred embodiment of a catchshowing the salient features,

FIG. 8 is a side view of the embodiment of FIG. 4,

FIG. 9 is a plan view of a second embodiment of the invention,

FIGS. 10, 11 and 12 are end, bottom and side views respectively of asecond embodiment of a catch showing salient features, and

FIGS. 13 and 14 are plan and side views of a third embodiment of a catchshowing salient features.

Referring to FIGS. 1, 2 and 3, the invention comprises a new combinationof electric hair-cutting shears 19 and a double comb 20 having teeth 22of a desired thickness. The outboard or leading double tooth 24 of saidcomb is inwardly extended to form hooks 26 that are adapted to engagethe outboard ends 28 of the stationary blade 30 of the double actionshears, thereby retaining the front end of said comb on the front end ofsaid shears.

A fastening bar 32 is secured to the double comb 20 by bolts 34 engagingthrough holes 36 in the comb in tapped holes 38 defined in the fasteningbar 32. A hook 40 is provided on the outer end of the fastening bar forengaging the end of the stationary blade of the shears. Shoulders 41 aredefined adjacent the end 42 of the fastening bar, and a triangular notch44 is defined intermediate said shoulders and the end 42.

A catch 46 is provided to engage the inboard end of the fastening bar 32up to said shoulders 41. The catch is bolted by bolts 47 to the shearsbody 48 through the stationary blade 30 to engage in tapped holes 50defined in said body 48. A transverse locking pin 52 is slidably mountedin a bushing 53 provided in catch body 55 and is adapted to engage anddisengage with notch 44 of the fastening bar 32. Said locking pin 52 hasa reverse end 56 that is chamfered to be retracted by the squared innerend 42 as it is inserted into a channeled recess 54 in said catch and tofit in said notch 44. A spring 57 is mounted in compression on saidtransverse locking pin 52 engaging against a side of the catch body 46and a split washer 58 mounted in a peripheral groove 60 defined aroundthe pin 52. A pushbutton end 62, oppositely disposed from the reversedchamfered end 56 of pin 52, is manually actuated against the compressionof said spring 57 to retract said chamfered end 56 from the notch 44 andthereby release the fastening bar 32 and attached double comb 20 forslidably retracting from engagement with the electric shears. See FIGS.4-8.

Referring to FIGS. 9-12 another embodiment of the invention comprises acatch 64 having a body 65 defining a channel 66 similar to channeledrecess 54 of the preferred embodiment, for receiving an end of afastening bar 32. A leaf spring 68 is rigidly attached by an end to thefastening bar 32. The oppositely disposed end is S shaped and adapted tosnap engage in the inboard curve 69 of said S a transverse lug 70 fixedto said catch body 65 when said end of the fastening bar 32 is fullyinserted in said channel 66. The outer curve 72 of said S serves as ahandle to lift the leaf spring 68 clear of lug 70 and thereby releasethe fastening bar and attached double comb 20" from the shears.

Referring to FIGS. 13 and 14, a third embodiment of the inventioncomprises another variation of latching the double comb on the shears. Acatch 74 having a body 76 defines a channel 78 similar to the channels54 and 66 of the preceding embodiments for receiving an end of afastening bar 32. A trunnion 80 is fixed to the body 76. An L-shapedlocking pin 82 is pivotally mounted on the trunnion 80 and a U-shapedspring 84 is compressed between one leg 81 of said L-shaped locking pin82 and the catch body 76. A fastening bar 86 having double combsattached at the outer end defines a hole 88 adapted to receive the endof depending leg of said locking pin 82. To operate, the end of leg 81is manually depressed against the compression of spring 84 to pivotlocking pin 82 in its trunnion 80 to lift depending leg 88 therebyallowing the insertion of the end of a fastening bar 86 into channel 78.Releasing the end of leg 81 causes the end of leg 90 to engage in saidhole 88 locking the fastening bar and attached double comb in theelectric shears. To release, one end of leg 81 is depressed and thefastening bar retracted.

To use the invention, the double comb 20 attached as previouslydescribed to the fastening bar 32, is held in one hand and the shears 19in the other. The end 42 of the fastening bar is inserted into thechanneled recess 54 (of the preferred embodiment) of the catch 46. Withthe fastening bar laying fiat against the stationary blade 30 of theshears, the fastening bar and attached double comb is pushed home up toshoulders 41 into the channeled recess 54, the hooked ends 26 of thecomb end teeth and the hooked end 40 of the fastening bar 32 engagingrespectively over the tips of the end stationary blade double teeth andthe end of the stationary blade. As the end 42 of the fastening barpasses into the recess it engages the chamfered reversed end 56 of thelocking pin 52 to retract the pin to snap engage in notch 64simultaneously with the hooked engagement of the comb teeth andfastening bar end, thereby locking both ends of the fastening bar andcomb to the shears. The invention is removed from the shears by manuallypressing the push button end 62 of the locking pin 52 and pulling thecomb to disengage the hooked ends from the stationary blade and thefastening bar from the channeled recess 54.

The second embodiment is operated similarly except the end 72 of theblade spring 68 is manually raised to release the end of the fasteningbar to slide from the channel recess.

The third embodiment does not snap engage and the catch 74 must bemanually operated as heretofore explained in order to engage anddisengage the invention to and from the shears.
